What problem does it solve? Before running autonomous implementation, teams need confidence that every required binary, OAuth session, and API token is present and valid. This Skill reads a versioned preflight manifest, executes all verification checks, auto-resolves what it can, and groups remaining human-required actions into a single blocking report. ## Core Features & Use Cases - Manifest-driven verification: Parses .specs/preflight.md with tooling, authentication, token, and custom check sections, then runs a 3-pass engine (parallel verify, sequential auto-resolve, grouped human blockers). - Stack-aware manifest generation: Regenerates the manifest from the project stack (_default.md), feature specs, and .env credential entries using a stack-to-checks catalog covering Cloudflare, Supabase, Vercel, Stripe, AWS, Playwright, and more. - Auto-fix and light modes: --fix installs missing tools via brew, cargo, npm, pip, or pipx and initializes simulators; --light re-verifies only expiring or new checks. - Use Case: Before launching an autonomous /spec-implement run on a Next.js + Supabase feature, run the preflight check to confirm node, supabase CLI, and stored tokens are valid, auto-install anything missing, and receive a READY verdict report. ## Quick Start Ask the AI to run the spec-preflight check to verify all tools, sessions, and tokens and write the readiness report before starting implementation.
